Note:
A total of 1023 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. EJ1/A is the Most Significant Bit and jumper EJ1/J is the Least Significant Bit. The jumpers have the following decimal values: EJ1/A=512, EJ1/B=256, EJ1/C=128, EJ1/D=64, EJ1/E=32, EJ1/F=16, EJ1/G=8, EJ1/H=4, EJ1/I=2, EJ1/J=1. Open the jumpers and add the values of the open jumpers to obtain the correct memory address. (Open=1, Closed=0)
